NAME

       XkbAddGeomColor -  Add one color name to an existing keyboard geometry description

SYNOPSIS

       XkbColorPtr XkbAddGeomColor (XkbGeometryPtr geom, _Xconst char *spec, unsigned int pixel);

ARGUMENTS

       geom   geometry to be updated

       spec   color to be added

       pixel  color to be added

DESCRIPTION

       Xkb  provides functions to add a single new element to the top-level keyboard geometry. In
       each case the num_ * fields of the corresponding structure  is  incremented  by  1.  These
       functions  do  not  change  sz_*  unless there is no more room in the array. Some of these
       functions fill in the values of the element's structure  from  the  arguments.  For  other
       functions, you must explicitly write code to fill the structure's elements.

       The  top-level  geometry  description  includes a list of geometry properties.  A geometry
       property associates an arbitrary string with an  equally  arbitrary  name.  Programs  that
       display  images  of  keyboards  can  use  geometry  properties  as hints, but they are not
       interpreted by Xkb. No other geometry structures refer to geometry properties.

       XkbAddGeomColor adds the specified color name and pixel to the  specified  geometry  geom.
       The top-level geometry description includes a list of up to MaxColors (32) color names.  A
       color name is a string whose interpretation is not specified by Xkb  and  neither  is  the
       pixel  value's  interpretation.  All  other geometry data structures refer to colors using
       their indices in this global list or pointers to colors  in  this  list.   XkbAddGeomColor
       returns NULL if any of the parameters is empty or if it was not able to allocate space for
       the color. To allocate space for an arbitrary number of colors  to  a  geometry,  use  the
       XkbAllocGeomColors function.

STRUCTURES

           typedef struct _XkbColor {
               unsigned int    pixel;      /* color */
               char *          spec;       /* color name */
           } XkbColorRec,*XkbColorPtr;
